NAME
    configure.sh

SYNOPSIS
    Prepares the build environment for Geogram/Vorpaline.
    
    - For Unix builds, the script creates 2 build trees for Debug and Release
    build in a 'build' sub directory under the project root.

    - For Windows builds, the script creates a single build tree that supports
    all cmake build types (Debug, Release, RelWithDebInfo, MinSizeRel)
    build in a 'build' sub directory under the project root.

USAGE
    configure.sh [options] build-platform

To build geogram:
  - go to build/$os-Release$build_name_suffix or build/$os-Debug$build_name_suffix
  - run 'make' or 'cmake --build .'

Note: local configuration can be specified in CMakeOptions.txt
(see CMakeOptions.txt.sample for an example)
You'll need to re-run configure.sh if you create or modify CMakeOptions.txt
